BRISTLE-BUNCH'ING Tool..

SPECIFICATION forming part of Letters-Patent No. 324,403, dated August 18, 1885.

Application tiled August :25, 1884. (Model.)

a mass of bristles contained in a suitable magazine the quantity of bristles required for a single tuft, and to form the tuft by bending the bunch of bristles double and then pushing the bight of this tuft into and through a split nozzle, by which the bight is presented in convenient position for entrance into one of the holes in the brush-back. f

My apparatus is intended to be fastened to suitable bench, and to be operated by a treadle to form and present the tufts successively.

The brush-back held in the hands of the operator is moved up to the nozzle in appropriate position successivelyto receive the bights of the tufts in the holes in the brush-back. rPhe nozzle yields backwardly as the brush- `back is pressed against it, and the continued protrus'ion of the bight of the tuft from the end of the split nozzle is insured by a mova-Y ble stop, which, after the tuft has been formed, holds the tuft stationary while its bight is being made to enter into a hole in the brushback, after which the stop retires, thus releasing the tuft, the bight of which is held in the hole vin the brush-back with sufficient friction to cause the tuft to be pulled out of the tube in which it is formed whenthe brush-back is moved backward.

The accompanying drawings of a bristlebunching tool containing my improvements vare as follows: Figure l is a side elevation exhibiting in transverse vertical section a portion of the bench to which the apparatus is its base a perforated to admit screws for fastening the frame to the operators bench. The frame is composed of the rib A, extending longitudinally across the base a, the upright A, the lateral arm A2, the standard A3, and the curved brace A4, bolted to the upper end of the upright A and to the upper end of the standard A, The front end of the rib A is perforated to receive the horizontal pin b, which serves as the axis of the oscillating doubling-lever B, to the upper end of which is aiixed the doubling-plate B', provided upon its front edge with the notch C. The radial distance ofthe rear end or heel ofthe doublingplate B from its axis of oscillation is less than the radial distance of the forward end from its axisA of oscillation.

Power to oscillate the doubling-lever is transmitted from an ordinary counterbalauced treadle by means of the pitman D, the bellcrank lever D, and the link D".

The upper end of the pitman D may be bifurcated, and its two legs, extending upward astride the flanged base of the frame, may be pivotally connected, respectively, ,with two bell-.crank levers respectively upon opposite sides of the frame, and having a common axis upon the pin d, inserted horizontally through the upright A. In this case twolinks will be employed to pivotally connect the upright arms of the bell-crank levers, respectively, with the doubling-lever B, the latter connection being by means of the pin d.

The range of forward motion of the doublinglever is fixed by means of the check-bolt b', adjustably inserted transversely through the lower arm of one bell-crank lever, or through a horizontal cross-bar connecting thevtwo bellcrank levers, if two are employed.""The intended adjustment is such that theimpact 4upon the rib Aof the lower end of the'check- IOC) and is thus presented in convenient position for entrance into one of the holes in the brushback. i

The forward end of the split tube E is the equivalent of the ordinary split nozzle used in bristle bnnehing and doubling apparatus. As heretofore employed the split nozzle has been rigidly aliixed to the arm which supported it. ln the present ease the split tube E has the capacity of yielding longitudinally when the brush-back pressed against its front end.

rlhe tube E is loosely contained in the split tubular arm F. projecting forward from the lower end of the standard A, and forming a continuation of the lateral arm A2 of the frame. The lateral arm A2, the tubular arm F, and the split tube E are curved in an are of a circle of which the axis ol' the doubling lever is the center.

The longitudinal slot in the concave side of the tube E and a similar slot in the tubular arm F and a corresponding groove Ain the under side of the lateral arm A2 are in the saule vertical plane, and define the path of the oscillating doublingplate B. i

'lhe front portion of the tubular arm F is provided upon its upper side with the slot F', through which there projects upward the ear E', attached tothe rear end ofthe tube E. The ear E is transversely perforated to receive the bight ofthe staple e, the two legs ot' which are loosely seated in the holes at e', formed in the lower part of the standard Ai". provided with a lixed collar, c2, and an expanding spiral spring, c, abutting at one end against the face of the standard A and at the other against the collar el.

rlhe tubular arm F is provided at its front end willi the earsff, which are transversely perforated to receive the pin or screw j", against which the earl is forced by the thrust of the expanding springs e c".

Immediately in the rear of the slot F the tubular arm F is provided with the hole Fto admit the tutt-stop G, which is dropped into the hole Fu during the latter part of the baekward excursion of the doubling-plate B,where it serves as a stop by wedging apart andcrowding the two legs of the loop of bristles against the sides of the tubular arm F in the' rear of the yielding tube lil, thus holding the luft stationary by friction du ring the time that the brush-back is being pressed against the forward end ofthe yielding tube E in the act of effecting the deposit ol' the bight o11 the` tuft into one ol" the holes in the brush-back. By the time the tul't has been received in the hole in the brush-back to the proper depth the tuft-stop G is moved upward, and the tuft is thereby released, so that when the brush-back is moved away from the tube E the tuft is drawn out of the tubular arm F by reason of the frietional hold ofthe sides of theholenpon the legs ofthe bight inserted therein.

rlhe stop G is anupwardly-yielding pin contained in the screw G', inserted in a vertical Each leg is hole tapped through the arm g, projecting forward l'rom the reciprocating carriage H, seated in a dovetailed groove, 71 formed inthe front face of the standard A".

Thenecessary up and down movement is i|nparted to the carriage H by means of thelinks H H', hung at their upper ends upon thehorizontal pivots H2 H2, and thus connected to the carriage H, and pivotally connected at their lower ends by the pins d with horizontal lugs H H3, projecting, respectively, from the opposite sides of the doubling-lever B. Then the doubling-lever swings forward,the carriage H slides upward', thus removing the stop G from the path of the doubling-plate B.

The bunches of bristles to form the doubled tufts are at each forward excursion ot' the doubling-plate successively,separated from a mass of bristles, l, arranged transversely across the rear face, l', of' the standard A, and held against the rear face thereof by the weighted flexible cords il z'. r

The upper ends ol' the cords are respectively attached to the hooks t" i, which are affixed to and -projeet downward from the nut i2, through which passes the vertical adjusting-screw i, the shank of which is loosely contained in a hole formed in the lug i", project ing forward from the upper end of the carriage H. The eordst' i are led from the hooks 'i' fi', respectively, through the vertical slots lf l2 iu the standard A", then downward through the slots l l and under the guide'pnlleys l* l", then backward and over the guide-pulleys l5 I5, and thence downward to the weight or weights hung upon the lower ends ofthe cords At each backward swing of the doublinglever, when the downward movement of the carriage H lowers the hooks t" i', the cordsi i are kept tant by the weight hung upon theln and crowd the mass ol' bristles downward, so that the lower portion of the mass is made to intersect t-he path of the doubling-plate B.

By each forward movementol' the doublingplate a bunch of bristles is caught in the middle by the notch. C and pushed away from the mass and bent double, and carried through the split tubular arm F and the split tube E, as 11a-s been explained.

During the backward movement of the doubling-lever the heel of the donbling'plate passes under the mass of bristles, which, as the doubling-plate moves backward, are wedged upward, but which spring downward in front of the notched end ofthe doubling-plate after the latter has completed its backward movement.

By appropriately turning the adjustingscrew i as .thennass of bristles I gradually di- IOO IIO

minishes in size, the hooks i z" can be adjnst- The mass of bristles I at the bottom bears upon the forwardly and downwardly inclined end k of thev gage-bar K, which, by means of its screw-thread K and the nut K2, is adjustable toward and from the corner formed by the junction of the rear face of the standard quired for a single bunch.

As an additional expedient for crowding downward into the path of the doubling-plate thequantity of bristles required for a bunch, the sliding bars L L are employed.

The forward ends, Z Z, of the bars L L are downwardly and backwardly inclined, and their rear ends, respectively, are pivotally secured to` the bifurcated upper end, M, of the rocking frame M, which rocks upon the horizontalaxis afforded by the pin M2, inserted transversely through the box M, bolted to the upright A.

Thev lower end, M3, of the rocking frame M" is pushed forward by the forward thrust of the spring m, except at the close of the backward excursion of the doubling-lever B, when a cross-bar, N, connecting the two links D2fD2, or a lug projecting backward from the doubling-lever, or the rear edge of the doublinglever itself, may strike against and rock backward the lower end, M3, of the rocking frame, thus rocking the upper end, M, in the opposite direction, and forcing forward the inclined ends Z Z of the bars L L against the bristles in the lower portion of the mass of bristles I, and resultant] y crowding them downward into the path of the doubling-plate. n

When for any reason it is desired to stop the feeding of bristles downward into the path of the doublingplate, the pivoted stop-lever O is rocked forward, thus forcing the bars L L under the mass of bristles I, and holding them up, notwithstanding continued oscillation of the doubling-lever and continued reci procation of the vertically-sliding carriage H.

The machine may thus be continuously worked merely for the purposes of adjustment or lubrication without removing the mass of bristles from it.

,Several of the individual devices described herein may be usefully employed in other forms of bristle bunching and doubling implements heretofore used. The doubling-plate or reciprocating notched pusher may be moved back and forth in a right line, instead of in 6o thegarc of a circle, and be combined with va yielding tube or nozzle, which is straight instead of curved.

I claim as my invention- 1. In apparatus for bunching and doubling bristles, a suitably-supported stationary tubular arm and a longitudinally-yielding tube or nozzle, in which the end of the said tubular varm is loosely inserted, in combination with a reciprocating notched pusherfor pushing the bight of the loop or tuft of bristles through the said stationary tubular arm, and through the said yielding tube or nozzle, substantially as shown and described.
